Jojo's Bizarre Adventure: Battle Tendency

From the introduction: The year is 1939 and the world is spiraling towards a new conflict. Nations begin to arm themselves as battles ignite, the ambitions of the German Reich plunging Europe and beyond into bloody war. It is those same ambitions that are due to awaken an ancient evil that has been asleep since the early days of the human race. The Nazis, in their search for arcane power to aid their imperial dreams, will uncover an ancient Pillarman in Mexico. This species once preyed on all of humanity and the chain of events started by human greed here will bring back our ancient foes, who wish to become the Ultimate Lifeforms.
